ATTACHMENT DEVICE.

Application tiled. December 27, 1922. Serial No, 609,300.

To all whom t may concern:

Be it known that I, HENRY P. Ronrnrs. a citizen of the United States, and a resident of the citv of New Yorln'county and State of New York, have invented certain new and useful Improvements in Attachment Devices, ot which the following, taken in connection with the accompanying drawings. is a specification.

This invention relates to improvements in attachment devices, and particularly7 to ani:- iliary means associated with -a support. adapted to removably hold one member in cooperative relation to another. t is particularly adapted for use with the mouthpieces of sound-conveying conduits ot dictaphones,7 or the like, an object being to provide such a device which will securely hold a mouthpiece in place, and at the saine time, will permitit to be readily7 removed, and as readily attached.

lt is customarj,7 with machines ot the dictaphone type tor several persons to use single machine.' each employing his own mouthpiece, and because ot the frequent insertion and removal ot the mouthpiece-and in some cases. because of variation in their size, or in the size ot their mounting-the attachment means would fail Vto properlv secure the mouthpiece. [Another object ot the invention, therefore7 is to provide an attachmentdevice which will not hecome deranged, or tail to function. because. ot re peated insertion and removal of the mouthpiece, and which will be compensating to take care of variations in size, particularly7 ot the mouthpieces.

A further object is to provide a device ot this character which will be extremeli7 simple in construction. and which ma;7 he used in connection with attachment means, at present in use, without materially7 changing such means.

`With the above and other objects in view, an embodiment ot the invention is shown in the accompanying' drawings, and this embodiment will be hereinafter more fully described with reterence thereto, and the invention pointed Vout in claims.

In the drawings- Fig. 1 is a side view, partlv in section, of the end ot a sound-conduit, having a mouthpiece, and showing the attachment device according to the present invention;

l and 3 is a detail perspective view et' the spring' clip emploved, and which is repre sentative et the essential feature oi" the device.

limilar reference numerals indicate corresponding' parts throughout the several fr;- ures of the drawing.

eterring` to the drawing'. the soundronduit illustrated is et the tvpe einplojy'ed in the commercial dictatingr machine, known as the dictaphone and is provided with a rigid tubular hand-grip 1G. the main portion ot the conduit (not shown) being' ilexible. At its extremitv. there is formed ai annular tlared inouthpiece-receiving portion 1 8, having' a pluralit;v oit slots, or cut-outs, lll. to provide resilient segments. in annular recess 15 is 'formed adjacent the base ot the portion 13, so that the side wall ot' said portion consists ot av series et spaced segment-s, each having` a y entering` portion and a portion.

The mouthpiece preterahlv or" glasf is suhstantiall)v hell-shaped. and is provit .i at its small end with an annulaif boss or bead 17 adapted to be pressed into the recess 15 ot t e portion 12, and wlierehv the n'iouthpiecc is ield in place.

release spring' clip I?. ot su ntiallv wishbone or V-shapc. but which could. oi: course. be made with one spring` member. or

Fig. 2 is a bottom plan view thereo' Fie:

with three or more, instead ot two, is secured to the hand grip 10 bj.' a screw 19, the head ot which presses upon the clip in a manner to tension it. so that its opposite end is constantlyT beingy pressed inwardlv. The side portions are disposed beneath the bend ot the handrrip 10. and are provided with hook-shaped ends 20 which entend through two of the slots 1li ot the portion 18, and into retaining relation with the bead 17 ot the mouthpiece.

vWhen using the device. in order to en- ,Q'age the mouthpiece with the portion 13, a portion of the bead 1.7 tiret engaged within the hooked ends ot the clip. whereupon the rest of the bead is pressed into the annular recess 15. the resilient segments oit the portion 13 yielding' sutlicientlj,7 for this purpose.

It will be seen that the spring clip exerts a pressure on the mouthpiece in a manner to securely press and retain the bead 17 in the recess 15, eren though it be of a diameter less than that of the recess.

`While, 'for the purpose of describing the inrention, the specific vattaching in ans has been described with conside 1able particularity, and for only one of its many uses, it is not to be understood that the invention is limited to the specific means thus shown and described. since it will be apparent to those skilled in the art that such means may, if desired, be varied within wide limits, without departing from the invention being defined in vthe appended claims.

`What is claimed, and for which Letters Patent of the United States is desired, is;

1. ln combination, amember haifing a mouthpiece-receiring portion., ainoiithpiece adapted to be engaged in saidv portion, and spring means separate from the mouthpiecereceiving portion adapted to rieldablj;v retain the vinoutlngiece therein.

Q. ln combination, a member having a monthpiece-receiving portion, including resilient mear. adapted to yieldablvv retain a mouthpiece therein. a mouthpiece adapted to be engaged in said portion, and auxiliar;7 resilient means adapted to cooperate with said first resilient means to retain the mouthpiece in said portion.

3. ln combination, a member Vhaving a month-piece-receiving portion, including annular resilient means adapted to yieldably retain a mouthpiece therein, a tubular mouthpiece adapted to be engaged peripherally by said resilent means, and auxiliary resilient means adapted to engage the mouthpiece at one point of its periphery and coo serate with said first resilient means to retain the mouthpiece in said portion.

4i. In combination, a member having a moutlipiece-receiving portion, comprising` a plurality of annularlr7 arranged spaced resilient sections, each having a recessed retaining'part and a i'esilent flared lguiding parta mouthpiece engaged in said portion and including an annular bead adaptedto be guided by said guiding part into engagement with said retaining part, and auxiliar;7 .retaining means secured to said member and extending into the space between two of said adjacent resilient sections and adapted to eii'gage said bead.

5. ln combination, a member having a mouthpiece"receiving portion, comprising a plurality7 of aninilzn'lj,v arranged spaced resilient sections, each having a recessed retaining partand a resilient flared guiding part, a mouthpiece engaged iii said portion and including an annular bead adapted to be guided by said guiding part into engagement with said retaining part, and a spring clip of substantiallyy il-shape secured at its bight to the member, and having its ends engaged in spaces between said resilientJ sec.- tions and engaging the bead of the mouthpiece.
